Sorry, Rendering from After Effects CS3. Working with Wick, we have it traced to a drive issue. If I render it to my "Huge Systems" 1.5tb Raid it gives me the error. If I take that same file and Copy it to my internal Raid it "Quick Imports" perfectly. This is a new issue that just started today for me. Disk permissions are the same on both raid drives. Disk utility and Disk warrior show no errors on the drive.

I have been using this drive for a long time, and clips that I previously used in media 100 will not import (although if they are already in the bin they play fine)

I have down graded to QT 7.5 and upgrade Media 100 to 12.7... and the issue remains. I will start further troubleshooting on Monday.
